1, the sleeve is the socket wrench for short. A special tool to tighten or loosen the screws on unloading. It has several internal hexagonal shaped sleeve and a sleeve or a few months on the handle structure, the order of priority within the hexagonal socket bolts depending on the model, you can choose according to need.
A water supply connection fittings, steel pipe can be used to connect with the cast iron pipe, etc. ......
2, reinforced connecting sleeve for a special product reinforced mechanical connection into cold extrusion sleeve, tapered threaded sleeve and straight thread sleeve.
Sleeve Feature
1 using the international 45 steel, high special manufacturing process, dimensional accuracy, reliable quality.
2 can be connected HRB335 and HRB400 grade level Ф16-Ф40mm ribbed steel bars.
3 After State Construction Engineering Quality Supervision and Inspection Center, to the JGJ107-2003 I-level joint standards.
4 standard, reverse threaded type, reducers three series of 52 varieties, to meet the architectural structure of horizontal, vertical, diagonal and other parts of the same diameter, reducers and adjustable length and direction the connecting steel demand.
Technical Features
Technical characteristics of the sleeve:
1, applies to withstand tension and compression forces of various types of two-way reinforced concrete Structure construction steel connections.
2, materials, energy, and without restricting the types of steel ingredients.
3, all-round connectivity.
4, in advance of prefabricated, factory jobs, do not take the duration, all-weather construction.
5, easy to operate, fast construction speed, can greatly shorten the construction period
Technical features reinforced connecting sleeve joint strength up to industry standards JGJ107-96 in A-level joint performance requirements. Thread-shaped, high precision, stable and reliable connection quality. Wide range of applications, for diameter 16-40mm. Ⅱ, Ⅲ grade steel in any direction with the diameter and position of connections. Adjustable: reverse threaded sleeve type applies to turn iron steel cage peer connection can not rotate at the rebar. Construction speed: thread processing in advance and on-site pre-fabrication, assembly and construction. Energy saving, pollution-free, safe and reliable construction.

Wrenches
Socket wrench: It is made with hexagon socket holes or multiple holes and twelve angle with the handle, extension bar, and other annexes, especially for very small or twisted position very deep depression bolts or nuts .
A socket wrench Category:
(1) according to size (refer to size square head): 1/4 〃, 3/8 〃, 1/2 〃 three sizes, 〃 inches mean a 〃 equal 25.4MM
(2) by length: long sleeve, short sleeve, E-shaped sleeve
3) Press the edge: 60 cents, 12 corner
(4) Appearance: single channel and Shuang'gou; knurled; straight; nickel and networks, etc.
(5) Applications: a manual socket wrenches and pneumatic wrenches (black, chrome molybdenum steel) of the points
surface treatments
(1) Bright Chrome: mirror-like, very bright
(2) Asian Chromium: matt
(3) Electrophoresis: black luminance. Is under the influence of an external DC power supply, so that charged particles in a dispersion medium in the anode to the cathode, or make directional movement to promote the separation of substances;
(4) phosphate: black, but dull. Immersed in the phosphating solution of the sleeve, forming a layer deposited on the surface of water-insoluble crystalline phosphate, which is a phosphate conversion process.
production process
Blank (a variety of specifications) - polish (remove burrs thorn, etc.) - Turning (mostly molding) - polished surface - engraving (eg knurled, printed LOGO, etc.) - the heat treatment (in order to increase its hardness ) - electroplating (nickel or chromium, etc.) - grab the black and other
distinguish good and bad
(1) look at the surface: Is there a flash, specifications meet the size criteria, without scratches, etc.
(2) ER: measuring torque and hardness with special tools; measure the size; salt spray test, etc.
Note: When the hexagon socket wrench or a second angle on the edge size is less than or equal to 32MM, the hardness value is not less than HRC39, when more than 32MM, hardness of not less than HRC35.
Auto sleeve parts
First, use the drive according to the classification:
1, pneumatic sleeve (also known as pneumatic sleeve)
2, manual sleeve
3, the electric sleeve: the electric socket wrench as a driving force.
Second, in accordance with the material classification
A chromium molybdenum steel (Chrome-Molybdenum Steel), chromium (Cr), molybdenum (Mo) and iron (Fe), carbon (C) alloys, high temperature processability, appearance after processing, can be hardened depth, an impact absorption performance, so often used in the manufacturing industry and large hand tools, pneumatic tools.
2, chrome vanadium steel (Chrome-Vanadium Steel), chrome vanadium steel chrome vanadium alloy elements are added to the alloy tool steel, mainly used in hand tools.
3,45 # carbon steel, the 45 steel, the carbon content of about 0.45%, due to good processing performance and multi-faceted treatment process to become commonly used in steel processing materials. Cr-Mo material above the optimum material (chromium-molybdenum steel) is the best material sleeve
